Actually it looks like my lame attempt was working; I'm just stupid. For
my purposes I want to delete hyperlinks and forms (in the end I want to
spit out data only as a CSV or something). Before deleting them, they're
not "empty".

After deleting them, of course, their containers look "empty" to me, and
I ask stupidly, "Why didn't these things go away?" Duh...

Sorry about that, folks.

That's still something I wonder; how can I identify elements which contain
data which is only whitespace. Any suggestions?

Thanks,
Len.
